Application filed December at, 1920.

To all whom it may concern.

Be it known that we, l-laiuiv F. HAMP- sriinn and FRANK B. CRANMER, citizens of the United States, both residing at Phila' delphia, in the county of Philadelphia and tltate of Pennsylvania, have invented certain new and useful Improvements in Delivery Attachments for Printing-Presses, of which the follo ing is a specification.

The object of this invention is to provide an improved delivery mechanism, particularly adapted for use in conjunction with printing presses, and designed for the purpose of conveying sheets from such a press so that they will. fall and pile upon one another with the side of each that has just been printed facing either downwardly or upwardly.

Frequently it is necessary to print sheets of paper, or the like, with progressive numbering, in which case it is desirable to deliver the said sheets from the press in a given order, generally with their faces down, so

that when the pile is inverted the lowest number appears upon the top sheet from which successive numbers increase in value downwardly, thus making it possible to as semble the numbered sheets with others in the desired order, or to feed the said sheets again into the press for a subsequent impression upon the reverse side, which latter may also comprise numbers in numerical progression, and which it is obvious would generally be desirable to run in the same order as those used in the first impression upon the obverse side.

Then again a job may be put upon the press which requires that the printed sheets be delivered in the usual way, namely, with their faces up and progressing from the lower to the upper part of the pile. This invention, therefore, provides an arrange ment whereby with but a slight alteration the sheets are taken as they are delivered from the press, and are stacked with either face up as may be desired.

And a further object is to provide a set of suitable racks for removably supporting a series of rolls, over which conveyor-belts pass to carry a printed sheet from the press, either directly to a tray in which the sheets are deposited face up and with ascending numbering upon them also progressing up- Specification of Letters Patent.

wardly, or toward a second belt passing between and around a second set of rolls and operative to turn the sheets face downward as they are delivered into a tray and with their numbers progressing upwardly through the pile.

With these and other objects in view, the present invention comprises further novel details of construction and operation hereinafter fully brought out when read in con junction with the accompanying drawings, in which Figure 1 is an elevation of one side of the preferred embodiment of this invention in operative association with any suitable standard type of printing-press; Fig. 2 is a elevation of the opposite side of the same; Fig. 3 is a top plan view of the improved delivery device together with that portion of a printing-press which propels the printed sheets from the latter toward and upon the former; Fig. 4 is a vertical section on the line 4 lof Fig. 3; Fig. 5 is a similar section on the line 55 of Fig. and Fig. 6 is a central vertical longitudinal section of the apparatus shown in Fig. 3.

Referring to Figs. 1 and 2, there is illus trated any standard type of a so-called job printing-press, comprising a table 1, upon which is placed a stack of paper, cards, or the like, 2, which are to be printed, and from which pile the individual sheets are removed successively by any wcll known means, either automatic or manually operated, until they in turn rest gainst the forward face of the platen 8, and while a ainst the ssidplaten the sheets receive an impression from type, cuts, or the like, removably secured within the chase-supporting members l over which the inking-rolls 5 pass to convey ink to the said type from the ink turn-table 6, supplied in turn from any suitable ink-reservoir and feed-mechanism 7.

The printingpress is designed to be run in any suitable manner as by an electricmotor (not shown), the same having its.

speed regulated by any desired form of rheostat or resistance box 8, while a drivingbelt 9 or other power-transmitting means extends from the said motor and rotates a pulley 10 upon one side of the press. The said belt-pulley rotates a fly-wheel 11 and is also secured to a shaft, and thereby also rotates a pinion 12 which meshes with and rotates a relatively large gear 13, to the outer surface of which is pivotally connected a pitman 14, having its opposite free end secured to the frame-work. 15 which supports the type in the turn-table, the ink-reservoir, and inking-rolls, to oscillate said last-named members as a unit toward and away from the platen 3 about a pivotal support 16 at the lower portion of the metal foundationframe 17 of the press.

The gear 13 also operates the paper-feeding mechanism 18 through a series of gears 19, and furthermore rotates a gear 20, which latter is keyed upon the same shaft and rotates a pinion 21 meshing with and operative to .rotate a relatively larger gear 22 carried by a shaft adjacent to and extending between the lower portions of the said frame 17. This last-named gear 22 s pivotally connected with a pitman 23, which extends toward and is pivotally connected at its outer end portion to a lever 24 which operates an oscillatory arm 25, provided in turn at its outer free end with paper-gripping jaws 26, the lower of which is adapted to be operated by a suitably actuated member 27 to grip the lower edge portion of a sheet 28 immediately after said sheet has re ceived an impression of the type and the type-supporting frame 4.

By reason of the rotary motion of the gear 22, the jaws 26 oscillate throughout an arc and remove the printed sheet from the platen 3 to the position shown in Figs. 1 and 2,where spaced fingers 29, between which the said jaws pass, remove the forward edge portion of the sheet from the latter and permit it to drop by gravity directly upon a .conveyer-belt 30, which comprises a portion of the improved delivery-mechanism.

The said conveyer-belt is rotatablymount ed beneath the press upon a roller 31, and extends from beneath said press between spaced upright members 32, which at their upper end support the fingers 29, and which also -removably support a shaft 33 carrying a series of wheels 33, which press downwardly upon the upper portion of the said conveyer-belt and serve both to prevent vibration of the said belt and also to press air from beneath the sheets 28 after they have fallen thereupon, said sheets being led beneath said wheels by means of a suitable partition 34 suspended from a member 35 connecting the upper portions of the members 32, and said partition ex tending downwardly to within a short distance of the said conveyer-belt.

At its opposite end the said belt passes over a roll 36, which is removably supported at its ends upon spaced frame-members 37 by means of a shaft which also car ries a pulley 38 connected by a suitable belt 39 to a pulley 40 keyed to a shaft 41,

which in turn is driven by means of a belt 42 from a pulley 43 carried by a shaft which also supports a pulley 44, rotated by means of a belt 45 passing also over a pulley 4G keyed to the same shaft with the gearwheel 22 of the printing-press.

When the improved delivery-mechanisin is arranged as shown in Fig. (3, the printed sheet 28 passes from the conveyor-belt 30 over a roll 47 and into a receptacle 4b,

where it may lie either flat as shown in the drawings upon a plate 49 or may be delivered so that the successive sheets slide toward and are held in alinement by direct contact with a member 50 unitarily secured to the said plate, and, if desired, also pivotally mounted at 51 to oscillate into any desired position as may be determined by a pin or other member inserted through the spaced apertures 52 or the like in the laterally opposite sides of the receptacle 4b.

The spaced frame-members 37 removably and revolubly support at their uppermost portions a roller 53 carried by a shaft 54, to which is also keyed a pulley 55 connected by means of a belt 56 and for the purpose of revolving the roller 47. Also secured to said last-named shaft is a pulley 56, which is connected by means of a belt 57 to a pulley 58 carried by the shaft 41.. The members 37 adjacent to their lowermost portions revolubly and removably support a shaft 59 carrying a roll 60, over which extends a conveyer-belt 61, which latter also extends over the roller 53 and is driven thereby, while said lastnamed conveyerbelt likewise engages the belt 30 as they together pass around the roll 36 throughout a portion of its circumference, the said belt 61 being driven by the roller and in turn rotating the roll 60.

That lower portion of each of the framemembers 37 which is nearest to the members 32 is provided with n'ieans for removably and rotatably supporting a shaft (32, carrying between said fran'ie-memhers a, series of wheels 63, and also a pulley (34. which is driven by means of a belt 65 from a pulley 66 also carried by the shaft 41. This said last-named shaft furthermore carries a pulley 67 which is connected by means of a belt 68 to a pulley 69 carried by the shaft 54.

hen the device is arranged as shown in Figs, 1, 2, 3 and 4, the printed sheets 28 are carried by means of the conveyorbelt 30 toward the roll 36, and are then engaged by the belt 61 and carried downwardly partially around the said roll 36, and removed from said lastnamed belt by means of a suitable substantially horizontally extending plate 70, through apertures in which extend the wheels (13. which wheels in turn catch the sheet and propel it toward and into a suitable tray formed by a bottom wall 71 and terminating downwardly in an upwardly extendingwall 72, against which the successive sheets slide and are piled one upon another in vertical alinernent.

lin the operation of the improved delivery mechanism when arranged with the conveyer-belt 61 present and the sheets deliw ered into the tray 7 172, it will be noted that the face of each sheet which has received the ink impression and has lain face upwardly upon the conveyer-belt 30 is finally delivered into the said tray with its face downwardly. Thus it will be obvious that, if the printing-press is provided with a numbering device for printing upon the successive sheets correspondingly progressing numbers and are delivered face downward upon the pile, the said pile as a whole may be removed at any desired intervals and inverted so that in inverted position the numbers of the sheets comprising the pile progress downwardly, while in the arrangement of the mechanism as shown in V Fig. 6 and previously described the sheets are delivered face-up within the receptacle 48, and with their numbers progressing from the bottom toward the top of the resulting pile.
